If god is made in man’s image then he would want to have a partner and children. As sons and daughters of god they to would be gods. If we are going to believe in the concept of god, then it makes sense to have numerous gods.
The Greeks and Romans had it right; hundreds of gods and goddesses each with its own characteristics. Nice gods, bad gods, amorous gods fond of ambrosia, and destructive gods. This way one god does not have to take the blame for bad things while claming to be good. The gods can pass the buck between themselves.
